(01. 251- The invention relates to valves and more parhanded, it is evident that, when the sleeve is ticularly to valves for use in connection with turned inrelation to the headers, these will be flexible tub'ings, such as for example rubber drawn together or forced apart according to hose. It has for its main object to provide a which way the sleeve is turned. Thus, when valve which, when attached to a hose, may be turned in one direction, the valve i8 will be 5 readily opened and closed, and adjusted to pass caused to be seated in the valve seat 20 and the fluid in any desired amount. Another obthus closing the valve, while if turned in the ject is to provide means in the valve which will opposite direction the valve will be removed from positively prevent leakage from any of the joints the valve seat, as in Fig. 3, and thus the valve 10 in the valve. will be opened.

5 headers and in the sleeve are right and left Having described the invention and its objects,

what I claim as new and wish to protect by Letters Patent is:

1. A valve of the class described comprising a front header and a rear header; a valve seat formed in one of said headers and a valve secured to the other; a sleeve interposed between the headers; means associated with the headers and the sleeve for drawing the headers together, to close the valve, and for separating the headers, to open the valve; and a distensible member secured between the inner ends of the headers and contained within'the sleeve.

2. A valve of the class described comprising a threaded front header and a threaded rear header; the threads of one header being right handed and the threads on the other being left handed; a valve seat formed in one of said headers and a valve secured to the other; an internally threaded sleeve secured on said headers; said sleeve adapted to be turned in one direction to close the valve and the opposite direction to open the valve; and a distensible member secured between the inner ends of the headers and contained within the sleeve.

3. A valve of the class described comprising a front header and a rear header; a valve seat formed in one of said headers and a valve secured to the other; a sleeve interposed between the headers; means associated with the headers and the sleeve for drawing the headers together, to close the valve, and for separating the headers, to open the valve; and a corrugated, flexible metal tube secured between the inner ends of the headers and contained within the sleeve.

4. A valve of the class described comprising a threaded front header and a threaded rear header; the threads of one header being right handed and the threads on the other being left handed; a valve seat formed in one of said headers and a valve secured to the other; an internally-threaded sleeve secured on said headers; said sleeve adapted to be turned in one direction to close the valve and in the opposite direction to open the valve; and a corrugated, flexible metal tube secured between the inner ends of the headers and contained within the sleeve.
